[Bug 579292] [NEW] Switch of user causes display problems

 

Public bug reported:

Binary package hint: xorg

When I updated the system from 9.2 to 10.04 the colours of the X11
Display were very strange - very yellow. I suspected the error in the
file xorg.conf and changed the default from 32 bits to 24 bits. After
that the display looked correct. When I switch a user from a running
session (gnome) to another user, gdm showed me a tiled window with four
quarters and only the upper left was correct. Then I experimented with
options for the display sections in the file xorg.conf and now the first
switch of a user somehow works. But if I switch back to the first user
the screen is "nearly" black. I clearly can see the mouse pointer and
suspect that everything else, except the display works.

Finally I decided to install a new Ubuntu system (no update) on the same computer but here the first user switch does not work.
The lower part shows "Ubuntu" and there is no gdm window to log in.
